The FAA is adopting a new airworthiness directive (AD) for certain Continental Aerospace Technologies Inc. C-125, C145, IO-360, IO-470, IO-550, O-300, O-470, TSIO-360 and TSIO-520 series model reciprocating engines and certain Continental Motors IO-520 series model reciprocating engines with a particular oil filter adapter installed. This AD was prompted by reports of two accidents resulting from power loss due to oil starvation. It requires replacing the oil filter adapter fiber gasket with an oil filter adapter copper gasket.
The effective date of the AD is March 29. Action is required before accumulating 50 flight hours after the effective date or at the next scheduled oil change after the effective date of this AD, whichever occurs first. View the complete AD here.
NAAA first reported on this AD when it was proposed in the October 14, 2021 eNewsletter.
